Towards Novel Insights in Lattice Field Theory with Explainable Machine Learning [PDF]

open access: yesPhysical Review D, 2020
Machine learning has the potential to aid our understanding of phase structures in lattice quantum field theories through the statistical analysis of Monte Carlo samples. Available algorithms, in particular those based on deep learning, often demonstrate

Review of lattice studies of resonances [PDF]

open access: yes, 2012
I review recent progress in extracting resonance parameters using lattice field theory, with an emphasis on determining hadron resonances from lattice quantum chromodynamics.

On the three-particle analog of the Lellouch-Lüscher formula

open access: yesJournal of High Energy Physics, 2021
Using non-relativistic effective field theory, we derive a three-particle analog of the Lellouch-Lüscher formula at the leading order. This formula relates the three-particle decay amplitudes in a finite volume with their infinite-volume counterparts and,

Quantum-field theories as representations of a single $^\ast$-algebra [PDF]

open access: yesUniversal Journal of Physics and Application 1, 179 - 188 (2013), 2013
We show that many well-known quantum field theories emerge as representations of a single $^\ast$-algebra. These include free quantum field theories in flat and curved space-times, lattice quantum field theories, Wightman quantum field theories, and string theories.

Radial lattice quantization of 3D ϕ4 field theory [PDF]

open access: yesPhysical Review D, 2020
The quantum extension of classical finite elements, referred to as quantum finite elements ({\bf QFE})~\cite{Brower:2018szu,Brower:2016vsl}, is applied to the radial quantization of 3d $\phi^4$ theory on a simplicial lattice for the $\mathbb R \times ...

Trailhead for quantum simulation of SU(3) Yang-Mills lattice gauge theory in the local multiplet basis [PDF]

open access: yesPhysical Review D, 2021
Maintaining local interactions in the quantum simulation of gauge field theories relegates most states in the Hilbert space to be unphysical -- theoretically benign, but experimentally difficult to avoid. Reformulations of the gauge fields can modify the

Relativistic-invariant formulation of the NREFT three-particle quantization condition

open access: yesJournal of High Energy Physics, 2022
A three-particle quantization condition on the lattice is written down in a manifestly relativistic-invariant form by using a generalization of the non-relativistic effective field theory (NREFT) approach.

SU(2) lattice gauge theory on a quantum annealer [PDF]

open access: yesPhys. Rev. D 104, 034501 (2021), 2021
Lattice gauge theory is an essential tool for strongly interacting non-Abelian fields, such as those in quantum chromodynamics where lattice results have been of central importance for several decades. Recent studies suggest that quantum computers could extend the reach of lattice gauge theory in dramatic ways, but the usefulness of quantum annealing ...

The flavor dependence of m ϱ /f π

open access: yesJournal of High Energy Physics, 2019
We calculate the m ϱ /f π ratio in the chiral and continuum limit for SU(3) gauge theory coupled to N f = 2, 3, 4, 5, 6 fermions in the fundamental representation. Keeping all systematic effects under full control we find no statistically significant N f

Simulating thimble regularization of lattice quantum field theories [PDF]

open access: yesProceedings of 34th annual International Symposium on Lattice Field Theory — PoS(LATTICE2016), 2017
Monte Carlo simulations of lattice quantum field theories on Lefschetz thimbles are non trivial. We discuss a new Monte Carlo algorithm based on the idea of computing contributions to the functional integral which come from complete flow lines. The latter are the steepest ascent paths attached to critical points, i.e.
